Migrate to central sonatype

[maybeec]

As a developer, I want to migrate from oss1 sonatype to central sonatype deployments.
To do so, following steps need to be implemented:

1. We need to migrate from the old maven plugin old nexus-staging-maven-plugin to the new maven plugin central-publishing-maven-plugin.
2. The new plugin automatically derives repository URLs and is not using . However, for SNAPSHOT deployments this seems not to be the case. Therefore you need to remove from your pom.xml.
3. The value of tags for the credentials needs to be "central"
4. make sure for SNAPSHOTs is pointing to https://central.sonatype.com/repository/maven-snapshots.
